Review on Dorman M3434 Brake Master Cylinder by Ron Kishore

This is the second one I have bought (both through Revain) for my 1952 Chevrolet and both are leaking. The first leaked on the top plate. I fixed it and moved on to other parts of my Chevy project. A few months later I noticed the piston was leaking so I ordered another one and installed it about 6 weeks ago. I just noticed that this is now leaking from the back of the unit as well. So now I have over $250 for a simple master cylinder replacement project and I'm still running out of money! I won't buy any other.
